It will feel like it's skipping if there is a broken tooth on a gear, it might also jam the chain.
internal- seems to be coming from trans.. I might just remove trans & chain, start and check

Do you have the belt-drive primary or the chain-drive one? I've been wrestling with how loose we're supposed to run the belts, on mine.

Generally belt tension shouldn't be more than a 1/4" depression in the longest part of the belt

THANK YOU!!! That is the FIRST time I've seen meaningful info on this! So far, it's been. "run it as loose as you can..".... Thanks again!

This is basically true of any belt drive system

That also sounds like a bushing issue, the bushing inside the clutch looses all its lubrication and starts to seize.
Check it out.
Conversion of Belt Drive, Bronze Bushing to Oilite Bushing
This is an easy conversion for a 15mm shaft motor. It requiries three new parts and about 30-45 minutes. The clutch works as follows: The bushing bronze or oilite is bolted against the bottom washer and locked to the motor shaft. The clutch bell rotates around the od of the bushing. For this...

Hey Jerry......I talked to about 6 belt dealers today and none of them could give me a simple answer to the question of belt tension. There's a big formula and a couple of special tools if you really want to get anal. I finally found a video where a belt dealer stated that the general rule of thumb is 1/64" depression for every 1" of lineal travel. On our belt drive tranys the distance between contact points on the pulleys is 4". Lay a ruler on top the two pulleys and at the half way point you should be able to press it down 1/16". New belts stretch right away so the need to recheck this soon is advised. This seems tight but you don't want the belt skipping which will tear the teeth off in a big hurry.
Another thing I learned.........our belts are p/n HTD 575-5M-15. The HTD is a registered trade mark for GATES . The other guys do not show this. Even HTD belts are made in China. This size belt only comes with a fiberglass reinforced thread. Kevlar is not available for us in this size.

Yes, a possible explanation is the brass bushing has run out of
grease and is binding. To test it, just pull the bike on the ground
with the motor off and check if it moves easily.
